↑Grousset, Rene, The Empire of the Steppes, (Rutgers University Press, 1991), 161,164; "..renewed the Seljuk attempt to found a great Turko-Persian empire in eastern Iran..", "It is to be noted that the Seljuks, those Turkomans who became sultans of Persia, did not Turkify Persia-no doubt because they did not wish to do so. On the contrary, it was they who voluntarily became Persians and who, in the manner of the great old Sassanid kings, strove to protect the Iranian populations from the plundering of Ghuzz bands and save Iranian culture from the Turkoman menace."
